Operating Characteristics
For the following conditions unless otherwise specified:
AVDD = DVDD = VDDIO = 3.0V to 3.6V; VSS = AVSS = DVSS, TAMB = +25°C; registers in default condition except
where otherwise specified or as necessary to enable the relevant sections of the device for half duplex
operation.
